int getspf(void) |
Unless the application is operating in WFDB_HIGHRES
mode
(see section setgvmode) and has then opened a multi-frequency record, this
function returns 1. For the case of a multi-frequency record being read
in high resolution mode, however, getspf
returns the number of
samples per signal per frame (hence sampfreq(NULL)/getspf()
is
the number of frames per second).
